Description

one

The invention relates to devices for cutting and chopping wood, shrub and other coarse squirrel agricultural vegetation and can be used in agriculture and forestry when clearing areas of undesirable vegetation, lightening crops, forage.

The aim of the invention is to increase productivity and quality of work,

 FIG. 1 is a schematic side view of a shredder; in fig. 2 - conveyor link; in fig. 3 - roller feed mechanism

A brush cutter consists of a frame 1 on which a shearing machine is mounted in the form of a cylindrical milling cutter 2, a conveying device in the form of a corrugated roller 3 and a conveyor 4, a roller feed mechanism in the form of a lower drum 5 with spring-loaded straps fixed between them and located between them cleaners 7 and the upper drum 8 with the pins 9 and the fingers 10 along its edges, connected through the vibrato springs 11, the hammer crusher, containing the rotor 12 with the hinged hammers 13, the counter knife 14, the casing with anti cutting elements 15 and deflector 16, bending device 17 and supporting skis 18. Conveyor 4 consists of articulated members of trough-shaped strips 19 supported through frames 20 on guide rails and fitted in the middle with gear teeth and hooks 2

In operation, the bending device 17 bends back the cut vegetation in the course of the movement of the shredder; the cutter 2 cuts off this vegetation and throws its butt part onto the corrugated roller 3 and the conveyor 4,

The trunks of the cut vegetation are located on the conveyor 4. Along it, facilitated by the gear hooks 21, and are fed to the rollers 5 and 8. In the chains to reduce the height of the cut, by eliminating the contact of the conveyor 4, the reverse branch with the cut-off vegetation of the plank 19 is made

trough-shaped and supported on guide frames 1 through rollers 20. Drum 5 - leading, drum 8 - driven, driven by engagement between lines 6 and 9, which in work pick up vegetation coming from conveyor 4 and divide it into segments 100-120 mm In this case, the vibrator 11, acting through the springs on the drum 8, facilitates cutting vegetation with sweats 6 and 9. In the cutting zone, the spring-loaded wipers 7 interact with the fingers 10 of the roller 8 and are recessed. When leaving the cutting zone and, therefore, engaging, the cleaning strips 7 are recessed under the action of the spring, pushing out the vegetation pieces to the shearing knife 14 and under the hammers 13 of the rotor 12 of the hammer mill. The wood pieces, when interacting with hammers, 12 and the conflicting elements 15, are ground to the desired state and through the deflector 16 due to inertial forces and the generated air flow are supplied, for example, to a vehicle.

The use of the proposed shredder makes it possible to increase the productivity of the work by eliminating the cutting apparatus being clogged and the quality of the work due to the liquid cut, eliminating losses and efficient shredding of woody vegetation.
